The cold-blooded captain of the starship Vortex in the Doctor's holonovel Photons Be Free, an unflattering character plainly modelled on Kathryn Janeway.
Captain Jenkins is a fictional character in Photons Be Free, the holonovel written by Voyager's Doctor in the episode Author, Author. The story puts the participant in the role of an emergency medical hologram aboard the USS Vortex, where organic officers treat him as property.
Jenkins looks and sounds like Janeway with different hair. In the novel she overrules the hologram's medical judgement and shoots a wounded crewman dead so that a favoured officer can be treated first.
The crew is appalled to find such thin disguises of themselves, and Janeway is far from amused. The Doctor at first defends the work as fiction, then agrees to revise it, though his publisher releases the original version.
